[MEncoder-users] Multi-threaded xvid-encoding on dual-core systems

[Markus Bonet]

Hi,

I am new to mencoder and used Windows so far for encoding TV-rips.
Actually I am getting used to mencoder and I am trying to find out how
my setup can profit from the 2 CPU-cores installed on my FC6 (x86_64).

Here is my setup:

mencoder: mencoder.x86_64                         1.0-0.66.rc1.lvn6
xvidcore: xvidcore.x86_64                         1.1.2-1.lvn6

I am testing with this simple command:
mencoder <TVRip>.ts -o /dev/null -ovc xvid -xvidencopts
bitrate=-175000:pass=1:threads=2 -oac mp3lame

But as far as I can see, only 1 CPU is used (top tells so). There isn't
any hint, that threads=n causes anything. Neither within the first pass
nor in the second.

I even compiled libxvid myself (without any configurations,
just ./configure) but there isn't any difference (I linked to the new
lib, fuser <myselfcomiledlibxvid> shows mencoder's pid during encoding).

Did I miss or misunderstood anything? Is there anything I need to add or
adjust?


Thanks in advance
Markus
